The Lowdown
G'day, Rusty here, looking at the surf on offer for the Jaconé area. We've got a solid run of waves coming through, with a real standout window that's got me pretty excited.
Imperial
Alright, so we kick off on Tuesday the 25th of August with some serious size. The swell is pumping at 8ft from the south, with a long 14-second period. The combined energy is a massive 2698, which is a lot of power. It's cross-offshore wind, so the waves will be holding their shape, but this is serious stuff only for experienced surfers. The water temp is sitting at 73°F, which is pretty normal for this time of year.
The real gem of the week looks to be Wednesday the 26th of August. First thing in the morning, we've got a glassy 7ft south swell coming in with a 12-second period. The wind is dead calm, totally glass. The energy is still strong at 2111. This is going to be clean, punchy, and absolutely perfect for the experienced crew. The afternoon builds to 8ft with a very long 15-second period and 3148 energy, but the wind gets a bit stronger cross-off. Still, that morning session is the standout.
Thursday the 27th of August morning is also a beauty. Glassy conditions again, with a 8ft south swell (14-second period, 2186 energy). Light wind from the north-northwest makes it perfect. The size is still up there, so continue to treat it with respect.
Friday the 28th of August sees the swell start to back off. The morning has a clean 4ft south swell with offshore winds, making for a gentler, more manageable session. The energy drops to 544, so it's moderate.
Saturday the 29th of August changes direction. The morning brings a 7ft swell from the east-northeast, but it's a short-period 8-second wind swell. The energy is 770. Offshore winds will keep it clean, but the short period means it'll be a bit more jumbled.
Sunday the 30th of August is similar. Morning offshore winds with a 7ft east-northeast swell (9-second period, 903 energy). Clean, but still a short-period swell.
Monday the 31st of August morning is worth a look. A 7ft east-northeast swell with an 8-second period, but light offshore winds keep it clean. The energy is 784.
After Monday, things get a bit messy for a few days with onshore winds and smaller, weaker swells. However, we get a nice reset on Thursday the 3rd of September. The morning has a clean 7ft south-southeast swell with a longer 11-second period and 966 energy, with offshore winds. That's a solid option for the first week of September.
We then see a gradual drop-off in size through the second week, but there are still some clean mornings. The 8th of September (Tuesday) morning is glassy with a 6ft east-northeast swell, and the 9th of September (Wednesday) morning has a clean 7ft east-northeast swell again. These are promising but less certain this far out.
Overall, the standout is definitely Wednesday morning, August 26th, for the glassy, powerful south swell. Keep an eye on the 3rd of September morning as well for a solid return of longer-period energy.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
